Installing ESP-r on Ubuntu 9.10
ESP-r, is an integrated modelling tool for the simulation of the thermal, visual and acoustic performance of buildings and the assessment of the energy use and gaseous emissions associated with the environmental control systems and constructional materials, in the words of its official website. In other words, it’s a computer program for modeling a building’s thermal and energy performance. It’s especially popular in Europe, particularly among academia.
Recently I wanted to install it on my laptop running Ubuntu 9.10 (Karmic Koala). The standalone installers provided on the main downloads website didn’t quite work, complaining about the lack of the libg2c library. Well of course it’s not available. It’s been obsoleted and is now deprecated.
Your best choice when installing ESP-r on Ubuntu is, quite frankly, to rebuild it from source. And it’s not complicated either. Here’s how I did it.
Check the project out from SVN:
$ svn co https://espr.svn.cvsdude.com/esp-r/trunk espr
$ cd espr/src
Ensure you have the required development libraries installed. In particular you will need libxml2-dev if you build with XML support and libX11-dev if you build the X version (which I recommend). Note that you really need the -dev packages, these contain header files required when compiling an application against those libraries.
Choose now an installation directory. Being the only user of my machine, I installed under ~/programs/esru, but you might want to install under /opt/esru. Now you should be able to build:
$ ./Install -d ~/programs/esru

Once the build is complete (took me an hour on a Asus 1005HA netbook), you should be able to run ESP-r:
